The purpose of this study to examine variation and development in hotel information system by longitudinal(2001, 2004, and 2007) research. Furthermore, This suggested a guide line to hotel practioners and reseachers by building a theoretical frame about analyze, direction of improvement, variables from Nolan's model, inverse proportion relationship between users' perception and control.
This study, first, is to arrange the conceptual structure through literature review for Nolan's growth stage model and understand status of Hotel Information System in five - star hotels in Seoul through every 3 years(2001,2004, and 2007) with benchmark variable.
Secondly, Among benchmark variable, There is no significant difference of information organization, planing &controling, and user's perception about inverse proportion relationship. In addition, this study found a equality that if hotel had higher information organization, planing & controling, hotel had higher stage of information system. Thirdly, this study found the hotel that had high level of HIS in 2001 and 2004, still maintain stable condition. On contrast, the hotel that had low level of HIS in 2001 and 2004, also still keep up same condition.
there is little bit of difference, but this study indicated that the hotel that changed their HIS or developed own HIS performed better than past.
Lastly, level of main purpose and application in five - star hotels in Seoul was located in at least over 3rd stage of Nolan's Growth stage Model as well as level of users. Some hotels spent huge amount of money for developing or changing HIS program to achieve effective hotel management.
